What's in the latest Firefox update? Mozilla revamps ad-tracker blocking controls
Mozilla today released Firefox 65 for Windows, macOS and Linux and called out new user controls for setting the desired level of anti-ad tracking by the browser.
Developers also patched seven vulnerabilities, three tagged as "Critical," Mozilla's highest threat ranking. "This results in the stream parser object being freed while still in use, leading to a potentially exploitable crash," Mozilla said, referring to a "use-after-free" bug in the browser.
Firefox 65, which can be downloaded from Mozilla's site, updates in the background, so most users need only relaunch the browser to get the latest version. To manually update, pull up the menu under the three horizontal bars at the upper right, then click the help icon (the question mark within a circle). Choose "About Firefox." The resulting page shows that the browser is either up to date or explains the refresh process.
